Mitsubishi PKA-A18HA Ignition Control Board
The main ignition control board may control gas intake, the ignition timing and some more sensing equipment. It has always been a vital circuit board that, over the years, has merged to become a piece of the main circuit board in order to have better control over the system.
What are some indications that my ignition control board is failing?
- Every other potential issue within the furnace checks out okay
- Communication from the home thermostat does not get to the control board
- Ignition cycle does not start even when called upon
